The results point out that the values of kinetic parameters are altered with the addition of Ti and C, which change the crystallization type from difficult nucleation and easy growth pattern to easy nucleation and difficult growth pattern, and this difficult nucleation and easy growth pattern may be the main reason why fine and even microstructure is gained in Ti and C doped alloys.The influences of Nd content, B content, partial substitution of Nd by Pr on the microstructure and magnetic properties have also been researched.

文章从动力学理论的观点揭示了合金显微结构与合金晶化动力学特性之间的关系，指出Ti和C添加改变了Nd9.4Fe79.6B11合金晶相析出时的动力学参量值，使合金晶化时晶相的析出方式由难形核易长大型加热管转变为易形核难长大型，这种易形核而难长大的晶化动力学特征，是Ti和C添加合金获得细小均匀的纳米晶结构的根本原因。

This very moment mood Real own because I very much treasure ourmeeting one another very very much, that has the certain fate, Ireally did not hope because of me the impulse idea, can cause oursentiment for a while to go bad Causes our friendship to change isnot good I really very much blame oneself, because own are the Chinese China'smatter manages again not not well also wants a type foreign countryold person to worry for me, I really very much do not have useful hereme only to be able with you to say again the sound sorry friend ofmine Hoped you can forgive my I since knew I have owed you to be very many always all do not have tobe able also to give you However this I have the difficulty to havein turn said with you, actually again I and you said previous two daysI had thought are very many, should I say with you, but when I makethe phone call for yours time I on regret But or said with you Againhere I hoped you do not blame me, I already very much to regret Triumphant I did not know I this action can let between us nearby thefriendship not be good Triumphant I knew the dissimilarity which weare the heart have cleverness but looked like you before to say,between us the communication really was very difficult to be verydifficult, but was in is difficult I also to hope which country nomatter you were at, perhaps worked I in there all to hope we couldhave the relation Between each other friendship is invariable, knewfinally is good..............

你好凯 此时此刻的心情。真实很很自己因为我很珍惜我们的相遇，那是有一定的缘分的，我真的不希望因为我的一时冲动的想法，会使我们的感情变坏。使我们的友谊变的不好。我真的很责备自己，因为自己是个中国人再中国的事办的不好还要样一个外国老人为我担心，我真的很没有用再这里我只能和您说声对不起我的朋友。希望你能够谅解我一次。我知道我欠你的很多一直以来都没有能够还给你。然而这依次我有困难有和你说，其实再我和你说的前两天我想了很多，我该不该和你说，可是当我把电话打给你的时候我就后悔。可是还是和你说了。再这里我希望你不要怪我，我已经很后悔了。凯我不知道我这次的举动会不会让我们之间的友谊边的不好。凯我知道我们是心有灵犀的但是就象你以前所说的一样，我们之间的沟通实在是很难很难，可是就算是在难我也希望不论你在哪个国家，或是在那里工作我都希望我们能有联系。彼此之间的友谊不变，知道最后好么。。。。。。。。。。。。。。

Solid geometry is difficult for middle school students to learn.

立体几何的学习是中学生学习难点之一，主要体现在图形难"看"、概念难懂、定理难用、习题难解。

But the bitter " of " difficult character of the man is not an isolated symptom absolutely, actually, the around of the bitter " in difficult character of occurrence male ", tired of the lumbar genu aching and limp that brings about by kidney empty, mind exhausted body, dazed tinnitus, bosom is fuggy short, insomnia make water of forgetful, frequent micturition tine of drop of drop of urgent, make water, deal with an offender shakes, limb cold Wei is cold wait for all sorts of symptoms to be able to appear in succession, must solve these anguish at the same time.

但男人的%26ldquo；难言之苦%26rdquo；绝不是一个孤立的症状，实际上，在出现男性%26ldquo；难言之苦%26rdquo；的前后，由肾虚而导致的腰膝酸软、神疲体倦、头昏耳鸣、胸闷气短、失眠健忘、尿频尿急、尿滴沥、发落齿摇、肢寒畏冷等各种症状便会相继出现%26mdash；%26mdash；%26mdash；解决男性的%26ldquo；难言之苦%26rdquo；，必须同时解决这些痛苦。

Results Of 49 cases,there were 36.7%of RA,8.2%of RAS,20.4%of RAEB,30.6%of RAEBT and 4.0%of CMML,respectively ,which showed the positive pathosis hemogenesis ,and had a trend of transforming to leukemia.

结果 49例中难治性贫血占36.7%，难治性贫血伴环状铁粒幼细胞增多占8.2%，原始细胞增多性难治性贫血占20.4%，转变中的RAEB占30.6%，慢性粒单型白血病占4.0%。

In order to understand these differences on gene transcript level, even to get the genes and their expression related to cell culture, we researched the differences of total mRNA of these tissues by RAPD-PCR, the result showed that the difference between embryo and head of nymphae was much closer than embyo with others, which was accorded to the time order of insect upgrown, and the tissue which is more different from embryo on transcript level ismore diiBcult to be cultured in vitro.

四种组织的培养难易程度和分离出的细胞形态的不同，说明存在着组织表达的差异，为了从转录水平上来认识它们的差异，甚而获得与细胞培养难易相关的基因及其表达产物，本实验还采用了RAPD分析的方法进行了这四种组织：中后期虫卵胚胎、若虫头部组织、成虫的精巢和卵巢的mRNA表达差异研究，结果表明：从发育方向上看，四种组织的表达差异有分化越大差异系数越大的趋势，而在相同条件下则越难培养。

The answer would be,"He is Sundari's Nanda."He was thus distinguished from Nanda the Cowherd and the other Nandas.

就是孙陀罗的难陀」，这就和牧牛难陀和其他的阿难陀，有分别的。

Sundari was a very gentle woman,and Nanda was a very affectionate man.So the two together were like fish and water-they never left each other's sight.

罗难陀，孙陀罗是个很温柔的女孩子；难陀是个很多情的男人，所以两个人就如鱼得水，寸步不离，因为这个，所以他的名字就叫「孙陀罗的难陀」。

This provides the basis for international cooperation in solving difficulties met in investigating and extraditing fugitives charged of corruption and recovering stolen state assets. It also helps China punish these corrupt officials according to law.

这将为解决中国查办涉外案件中的&调查取证难、人员引渡难、资金返还难&提供了国际合作的依据，从而有助于将潜逃国外的腐败犯罪嫌疑人引渡回国，给予应得的惩罚。

However in the recent 20 years, chaos in the public health domain made person felt worried about the economic and society development:"SARS" giving people a profound lesson with eternal bitterness, the schistosome and the tuberculosis resurging......

然而近20年来，公共卫生领域里的混乱却令人对经济社会的可持续发展感到担忧：&非典&的教训刻骨铭心，血吸虫病、结核病死灰复燃……特别是近10年，&看病难、住院难、手术难&的情况没有根本改变，个人卫生保健支出迅猛增长，令普通百姓难以承受。
